Title: Improvements in or relating to the manufacture of hydrogen peroxide by cathodic reduction of oxygen
IPC: C25B1/30
Filed: 1928-05-04
Abstract: 316,919. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). May 4, 1928. Hydrogen peroxide, obtaining.-In the process for obtaining hydrogen peroxide by the passage of a vigorous stream of oxygen or of a gas containing oxygen through the cathode space of an electrolytic cell, the excess gas passing through the cell is used in the concentration and distillation of the hydrogen peroxide solution obtained. The evaporation apparatus may consist of a trickling tower heated to 35‹ C. through which a counter current of the gas passes, the outflowing gas being cooled to the temperature of the cell, e.g. 13‹ C., before return thereto. Alternatively, the temperature may be the same as in the cell, the gas being dried before entering the evaporation apparatus. The hydrogen peroxide solution mav be concentrated from 1 per cent to 30 per cent strength in this way. An already concentrated solution of hydrogen peroxide may be passed through a trickling tower in contact with a stream of the dried oxygen. The current of gas leaving the tower laden with water and hydrogen peroxide vapour is cooled to obtain a condensate mainly consisting of hydrogen peroxide and is then used for further concentration of a dilute solution. Active silicic acid may be used in drying the gas. Specification 264,535, [Class 32, Distilling &c.], is referred to.

Patent GB-1089315-A (GB)
Title: Image amplification
IPC: H01L31/14
Filed: 1966-03-25
Abstract: An image converter comprises a photo-conductive layer between electrodes, one transparent and one opaque, and a phosphor layer; an input image formed on the photo-conductor is converted by the potential maintained across the electrodes into a heat pattern in the photo-conductive layer, which is in thermal contact with the phosphor layer, and this heat pattern modifies the light output of the phosphor layer, which is not traversed by the current between the electrodes.  The input may be ultra-violet, infra-red, visible or X-ray radiation, and the output may be a negative, e.g. where an ultra-violet source is used to excite the phosphor, and the applied thermal image quenches the luminescence; or a positive, e.g. where the fluoresence is enhanced by temperature, or where the phosphor stores the excitation energy, and subsequently releases it as visible light, when the phosphor temperature increases. An electro-luminescent layer may be provided between the photo-conductive layer and the opaque electrode; this layer is excited by the increase of current upon illumination of the photo-conductive layer, and the light output of this layer then further excites the photo-conductive layer, i.e. gives an optical feedback. Examples use a stannic oxide coated glass, a 0.01 inch thick layer of cadmium sulphide photo-conductor, a thin layer of conductive silver paste and a thermo-sensitive phosphor comprising 49% zinc sulphide, 49% cadmium sulphide, 2% sodium chloride, 400 ppm. silver and 2 ppm. nickel in a binder.  Other photo-conductors mentioned are CdS:Cu, ZnO, selenium, and the sulphides and selenides of lead and selenium.  In one embodiment, the transparent electrode consists of stannic oxide strips, 0.001 inch thick, 0.010 inch wide, 0.025 inch pitch, with a 0.007 inch photo-conductive layer and a 0.001 inch layer of electro-luminescent manganese-doped zinc sulphide in a silicone alkyl resin.

Title: Improvements relating to electric circuit arrangements for indicating the occurrenceof fault or other abnormal conditions
Inventor: STALLWORTHY FRANK ALLEN
IPC: G07C3/14
Filed: 1958-04-25
Abstract: 844,239. Automatic exchange systems. SIEMENS EDISON SWAN Ltd. Jan. 23, 1959 [April 25, 1958], No. 13230/58. Class 40 (4). [Also in Group XIX] In a system in which operations can fall into desirable and undesirable categories, the latter type are caused to charge a condenser and the former are caused to discharge the condenser, and arrangements are made for an indication to be given if the charge on the condenser exceeds a predetermined limit corresponding to an undesirably high proportion of undesirable operations. As described the invention is applied to a register-sender which receives digits in a twoout-of-five code, a signal containing other than two elements being undesirable and being either rejected with the reversion of a " re-order signal " or transmitted to a subsequent receiver which reverts a re-order signal to the registersender under consideration. In the diagram shown, these conditions cause the operation of one or other of the contacts br, bd (relay windings, not shown). Operation of the circuit is initiated by the throwing of key KR which discharges the condenser C whereupon the valve V 1  conducts to operate ER. When KR is released condenser C charges by grid current to a datum potential above which it cannot rise, but ER remains operated. When the register sender is seized, contact td is operated to bring up FT. When the register sender is released, contacts fn operate to bring up A for the duration of the release time of FT. Relay A connects up the charge/discharge circuit of condenser C. If either bd or br operate due to undesirable operation the condenser C charges negatively from potential derived over R 6  from the potentiometer R 1 , R 5 , R 2 . In a desirable operation, however, the condenser discharges via R 6 , R 7 . The discharge rate is arranged to be only a fraction of the charge rate. If the condenser C charges sufficiently, it cuts off V 1  to release ER and give an alarm over lead 1. The potentiometer R 5  may be adjusted so that, say, four initial undesirable actions are necessary to set the alarm off. For effecting the adjustment, plug PL is transferred from the busy jack TJB1 to TJB2 and key KT thrown to connect up lamp LP and to simulate the undesirable operation condition in the charge/discharge circuit. The potentiometer R 5  is then adjusted until the lamp is lit after the key KSR has been thrown four times, each throw of the latter key causing A to operate as though the register had been seized and released.

Title: Improvements in wire coiling machines
IPC: B21F3/06
Filed: 1937-05-11
Abstract: 495,388. Making wire springs. STEVENS, A. H. (Young Spring & Wire Corporation, L. A.) May 11, 1937, No. 13406. [Classes 83 ii) and 83 (iv)] In a machine for forming coil springs of varied shape, wire 13 is fed between rollers 11, 12, Fig. 1, through a guide 15, and is acted upon by a coiler block 16. The upper feed roll .11 is mounted in bearings floatingly mounted and raised and lowered into driving engagement with the wire by a roller 18 and a cam 17, Fig. 12. The cam comprises two members 19, 20, the former of which is adjustable on a hub 21, and is fixed by screws 22. A scale 23 is provided on the member 19 and a pointer 24 on the member 20, the members being complementary as to lift and dwell, adjustment of the dwell determining the length of feed. The coiler block 16 is mounted on a rock shaft 25, Fig. 2, and is operatively associated with a pitch block 26, on a slide rod actuated by a pivoted arm 28 from a hand wheel 32. A lever 35 with a grooved upper edge for a follower 37 is carried by a rocker 38 adjustably attached to an arm 39 on the shaft 25. Scale indicia facilitate adjustment. A vertically movable carriage 46 guided in a slideway 47 is actuated by a cam 48 on a shaft 50 driven in synchronism with the feed rolls. The adjustment of a stop 52 determines the period of rest of the carriage. A dwell portion 53 on the cam allows for the actuation of the cut-off mechanism. A scale on the cam 48 and a pointer 54 show other adjustment for different lengths of spring. The scale is numbered on one side of the cam from the dwell portion to the highest lift portion and on the other side from lift to dwell, these two sides being used for different shapes of spring. To produce springs varying from true cone shape means are produced in conjunction with the cam 48 to vary the resultant action. A slide 65 in the carriage 46 reciprocates horizontally or at right-angles to the path of the carriage and has an arm 67 with a roller engaging a cam slot 69 on a lever 57, the movement of the lever being a resultant of the two actions. An adjustable follower on the slide 65 coacts with adjustable shaping members 73 pivotally mounted on an adjustable slide 75. As the carriage is reciprocated by the cam the follower travels up and down on the shaping members 73. One part of the spring is formed during upward movement of the carriage 46 and the other during downward movement. To produce a spring with double cone shape the forming members are brought into alignment. One part of the spring may be cylindrical and the remainder in the form of a double cone. Many other springs may be formed such as the hour glass type, or the type of substantially cylindrical form with tapered ends or of single cone type.
